uNilfl-Eflt SJTKA CARL C. HIN'KLEY, OF DETROIT} MIGHIGAN.

GOVERNOR;

Application filed September 27, 1919.

To all whom it may concern.

Beit known thatl, CARnC. HINKLEY, a citizen of the UnitedStates of America, re sidin at Detroit, in the county of \Vayne, and gtate of Michigan, have invented cer tain new and useful Improvements in Governors,,.of which the following is a specificati0n,- reference beinghad therein to the accompanying drawings The invention relates to governors and particularlyto governor mechanism designed for use. in internal combustion engines. In governors heretofore constructed the throttle valves have been actuated at only approximately a predetermined engine speed That is if 'the governor is .set to actuate the throttle valveat 1200 revolutions per minute of the engine it has been found. that the throttle valve does no necessarily begin to close at. this speed but is liable to begin to close at 1100 orlilQO revolutions per minute. Witlumy construction this objectionablefeature is overcome and the throttle valve be.- gins to close; at the predetermined speed of engine. Another object is to provide a construction in which a tortion spring prorides the yieldable resistance-to the outward or lateral movement of theweight members n thegovernor proper. A further object is the provision of means for varying. the resistance to movementof the throttle'valve. A. stillfurther object is the provision of a compact construction in which the part-sare inclosed so that they are protected bot-hv from theweather and from being tampered with. Other objects of ,the invention reside in the novel arrangements and combinations of partsas more fully hereinafter set forth.

manifold 2. in the leg of which isloeated the throttle valveil. 4 is theigovernor'mech anism driven from the engine and controlw. ling the movement of the throttleralve. 3 dependlng upon the speed at whiohthe'englue is running.

he governor proper is preferably located at the rear of:the. eng ine.- and driven tfrom a shaft having a.high' rate. of rotation. Indetail, is a ertical shaft mounted at its upper and lower endsin the bearingsfi and. i respectively which are. in turn mounted in the casing. 8. 9 are gear teethupon-the lower end of the shafti5 andmeshing with the teeth of the gear 10 which is drivenpreferably. from the cam shaftiohtheengine (not shown). 11 is a huhmembenfi gedly. sef cured to the shaft 5 and having the flange 12,. which latter is provided with, depending lugs 13 upon which are pivotallymounted the; hell crank weight members 14; These bell, crank weight members havewthevdep ending, weight arms 15 and theinwardly extending arms lfinrhich-are preferably provided-with rollers 17 at their inner ends, Upon rotation of the shafto the bell crank weight. arms l-t will also be rotaterh. thereby. tending. to throw laterally outward theweight arms in which will. move the inwardly extending arms 16 downwardly. Movement in this direction. is limited by means of the. lugs.

18 upon thebell, crankweight .arms which will engage, the. periphery of;the flange; 12. 19 is a thrust member sleeved upon the. shaft 5, and as shown this thrnst member comprises the sleeve 20 keyed to the shaft: and having its upper end in-engagement with the rollers 17. 21. and 22 are plates between which are.l0cated the balls23. The u per plate 21 engages the lower end of the s eve: 20 while the lower surface of the lower plate '22 is adapted to rest upon the oke 24-which has its furcations embracing t e shaft 5.

25 is a shaft extending transversely of the engine 1 at its rear and rotatablymounted in the casing S. Yon-rotatahly secured to uni end of this shaft is the vertically extending rock arm 26 enclosed Within the cusingQT at the side of the casing-R; This rock :zrm 2G is connected to the rod 28 by a ball and other joint '29. The rod 28 extends longitudinally at the sides of the engine and is connected at its rear end to the prank arm, n). which is nou-rotatably secured to the throttle valve 3. The middle of the shaft 2-3 has non-rotatahly mounted thereon the yoke 24, while the opposite end of the shaft 25 is engaged by the tortion spring 31 which yieldably resists rotation of the shaft. In detail, this opposite end of the shaft 25 is provided with the longitudinally extending central slot 32 in which the inner end of the tortion spring 31 engages The opposite end 34 of the tortion spring 31 engages in a corresponding slot 35 in the threaded menr ber 36 extending through the depending flange 37 upon the arm 38 of the casing 8, The coils (if the tortion spring surround the adjacent ends of the shaft 25 and threaded member 36. V

For the purpose of varying the tension of the tortioii spring 31. the rock arm 39 is provided engaging the threaded member 36. 40 is a uadrant secured to the arm and having tihe series of apertures 41 concentric with the axis of the threaded member 36 and opposite the rock arm 39. The rock arm 39 is provided with a suitable spring pressed plunger 42, which is adapted to engage in the apertures 41 to lock the rock arm 39 in adjusted position. 43 is a collar having an annular groove in its outer face engaged by the screw 43 for retaining the collar in the outer end of the arm 38. The threaded member 36 threadedly engages the collar 43 and the rock arm 39, the latter be ing locked in position upon the threaded member by the lock nut 44. By rocking the arm 39 the threaded member 36 will be correspondingly rocked thereby increasing or decreasing the tension of the spring 31 by respectively coiling or uncoiling the same.

The plunger 42 may be held from engagement in the apertures 41. of the quadrant 4t), and a suitable connection 44 may be provided pivotall Y secured to the end of the rock arm 39 exten ing above the quadrant 40 for rocking the rock arm. This connection may be extended to a place to be conveniently operated by the driver of the vehicle, such as the dash.

For the purpose of securing a uniform time of operation of the throttle valve depending upon the engine speed and the predetermined adjustment of the governor the coil tension spring 45 is provided within the casin 46 at the side of the leg of the intake manifold 2. The inner end of this tension spring is secured to the crank 30. while the outer end is secured to the stem 47 extending through the end of the casing 46 and suitably secured thereto. The throttle valve actuates this auxiliary spring which yieldably resists movement of the throttle valve. the opera tion being such that the throttle valve will close constantly at the predelerniinwl rate of engine speed and will not vary as in gov crnpr construct ions heretofore manufa tur d. in fact. it has been found that with the present construction if this second or auxi iar v pring is mitted the thr ttle valve \vill beginto close at different speeds ofrotation of the engine instead of beginning to close constantly at a predetermined speed of the engine.

For the purpose of preventing tampering of the governor mechanism the tube 48 is provided at the side of the engine and extending between the casing 27 and the leg of the intake manifold 2, this tube enclosing the rod 28. The tube 50 is also provided enclosing the tortion spring 31. Thus with this construction, after the springs have been adjusted to secure an actuation of the throttle valve at a predetermined rate of engine speed the adjustment means may be suitably locked or sealed and it will be impossible to tamper with the governor mechanism to vary the time of actuation of the throttle valve.

The governor proper is lubricated by means of lubricant forced through the aperture 51 in the bearing 6. This lubricant descends upon the shaft 5 and is thrown laterally out by centrifugal force and thoroughly lubricates all the parts Within the asing 8. The lubricant then passes through the ball bearing 7 at the lower end of the shaft 5 and lubricates the gears 9 and 10 moving back to the crankcase of the engine.
